3D Selection Vault

Gaze&Wall

Also known as Wall&Gaze, Gaze + Plane

Look at the target and push a see-through wall to its depth with a hand ray; the gazed target closest to the wall is selected.

How it works

Gaze preselects all targets within 1.5 degrees of the gaze ray. A large semi-transparent wall, positioned in depth by a downward hand ray pointed at the floor, then picks the preselected target closest to it. If gaze finds only one target, the wall is not needed. In the comparative study it was faster and less error-prone than gesture-only alternatives. Hand tracking in an HMD; the non-dominant hand confirms with a pinch. Targets in a dense 2 m sphere 3 m away.
